ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent N 0. 691,855, dated January 28, 1902.

Application filed November 9, 1900. Serial No. 35,965. (No model.)

To aZZ whom it may concern:

Be it known that I, KARL GUSIAF Gus- A TAFSSON, engineer, of Sibyllegatan 4, Stockholm, in the Kingdom of Sweden, have invented Improvements in Acetylene-Gas-Generating Apparatus; and I do hereby declare the nature of my invention and in what manduced cylindrical part B, the latter terminating at its lower end in a funnel-shaped bottom 0. In the upper portion A of the casing there is a chamber a, containing a grateb for supporting the carbid, the said grate being supported at m by a partition-wall m, extending concentrically within the cylindrical casing A and forming practically an extension of the lower casing B. The grate b is also supported by stays m from the cover 0 of the buoy. A purifier h surmounts the easing Aand communicates with the space above the grate b, and above the purifier h a framework D is arranged, Which'supports the lamp E, to which the gas is conveyed from the space above the grate by the pipe 0. Below the grate b a funnel-shaped wall e is arranged, having a lower discharge-opening at e.

Outside of the concentric partition-wall m and in the upper part of the chamber A a chamber m is formed, which communicates through a pipe 0 with the interior of the reduced casing B of the buoy, and in the lower part of the upper casing A and extending circumferentially thereof an air-chamber is provided, which is separated from the chamber m by the wall a.

The sediment from the carbid may be discharged from the buoy through a cook 70, arranged at the outlet in the bottom 0. This cock may be operated from't-he surface of the water in which the buoy is floating through the chains 70. The specified gravity of the structure and the water-chamber n is so proportioned that the buoy will float at a definite water-level when cock is is open to allow the water to enter the buoy freely; The waterlevel is shown in the drawing both within and without the apparatus, and it will be seen that the grate b is located at a point above the normal water-level, so that the carbid supported by the grating will be free from direct contact with the Water and will be affected only by the evaporation from the said water. When the gas-pressure increases beyond that required, the water in the chamber a will be forced downward and up into the chamber m, thus reducing the superficial area of the water in the chamber a for evaporation. The generation of the gas is thus decreased until the pressure is reduced to thenormal point. The water will then rise in the chamber a and fall in the chamber m. It will be understood thatwhen the buoy is floated the cock is is closed after a sufficient amount of water has been let into the buoy. The said cock, however, may be omitted and the water have free access to the interior of the casing.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that What I claim is 1. A lighting-buoy consisting of a hollow casing, means provided on said casing for floating the same at a substantially definite water-level, a grate for holding calcium carbid within said casing, the said grate being supported at a point above the normal waterlevel in the casing and gas-consuming means provided on said casing for burning the gas produced, substantially as described.

2. A lighting-buoy consisting of a hollow casing, means provided on said casing for floating the same at a substantially definite water-level, comprising an air-chamber, a grate for holding calcium carbid within said casing, the said grate being supported at a point above the normal water-level in the easing and gas-consuming means provided on said casing for burning the gas produced, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses. 1

KARL GUSTAF GUSTAFSSON.
